REUBEN HENRY ANDREVS, OF VASHINGTON, DISTRIOT OF OOLUMBIA.

WOD=WORKlNG MACHINE.

SPECIFICA'I'ION forming part of Letters Patent No. 299,190, datel May27, 1884.

Application filcd October 2, 1883. (No model.)

To all witam it may conccrn:

Be it known that I, REUBEN I-I. ANDREWs, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Iniprovenients in Vood-/Vorking Machines, ofwhich the following is a specification, reference being had therein tothe acconipanying drawings.

This invention relat-es to Wood-working niachines, and is speciallyintended to bc applied to a machine of the character shown in my PatentNo. 250,181, of November 29, 1881, which I call my complete Wood-workinginachine The object of the present invention is to improve the driving`inechanisni for the shaping or friezing tool of such a nxachine as isabove indicated.

The particular' details of construction which constitutc my presentinvention will be hereinafter pointed out in the claims.

In the drawings, Figure l is a plan, partly in section, showing` suchparts of the driving inechanisni as constitute my present improvement,the table of the machine being` rcnioved. Fig. 2 is an end view of themachine, showing only such parts of the machine as illustrate niypresent invention. Fig. 3 is a side View of the shipper-lever and asection of the bevel-pulley mounted thereon. Fig. 4 is a plan view ofbell-crank lever. Fig. 5 is a detail showing` the arin which carriesidler-pulley i.

A represents the frame of the machine; G, the shaping-cutter niounted onrotating shaft G', as in niy patent referred to.

a is a driving-shaft, provided with two bevcl friction-pulleys, Z) c, asshown.

A bevcl friction-pulley, d, is journaled on a standard, (1/, which iscarried by a shipperlever, c. This lever is pivoted at e' to a crossbar,A', of the frame. The end c2 of the lever c is pivoted to an arin, f',of bell-crank lever f, which is provided with a slot, fz, for thereception of the projeotion ei* of lever e The bell-crank lever f ispivoted at x to a crossbar, A2, of the frame. Thus the movenient ofbell-crank lever f from the position shown in full lines to the positionshown in dotted lines in Fig. l will throw the pulley d out of contactwith pulley b, and if the lever is moved far enough said pulley d willbe thrown into contact with pulley c and driven in reverse direction, orin intermediate position between Z) and c the pulley d will be at rest.

The belt g leads from pulley d around the guide or idler pulleys h z' tothe pulley g', so as to drive said pulley and its shaft andshaping-cutter. The relation of pulley d to the guide-pulleys or idlersh 'i is such that the tension of the belt g will be substantially thesame,whichever one of pulleys b c maybe en.- gaged by said pulley (Z.The idler-pulley z, which serves to tighten belt g, is carried on aspindle, z, on arin K. Said arni K has a sleeve which embraces thestationary shaft h', and is secured thereto by set-sorew. Thus thearin'K may be swung on shaft h'in the direction of the arrow, and thebelt thereby be tightened.

The bevcl friction-pulleys b c d may be faced with wood, leather, orother suitable materlal.

The end of bell-crank lever f is so located as to be within convenientreach of the foot of the operator.

The cutter G is of the kind adapted to cut whichever direction its shaftis driven.

I clain1- 1. The combination, with a shaping-cutter and the driving-beltthereof, of bevcl frictlonpulleys, as Z) c, a bevcl friction-pulleyarranged, as described, between the two, so as to be brought in contactwith either, a shipper-lever which carries said intermediatebevel-pulley, and a lever for Operating sald shipper-lever,substantially as desoribed.

2. The bell-crank lever pivoted to the frarne and to the shipper-lever,as shown, the shlpper-lever carrying the friction driving-pulley, asdescribed, the friction-pulleys arranged to be engaged by saiddriving-pnlley, the guidepulleys arranged as shown, the belt, and thecutter-carrying shaft and pulley, all arranged and combined in aWood-working machine of the Character described, as andfor the purposesset forth.

3. The combination, with the cutter driving-pulley, of the frictiondriving-pulley and its shifting` inechanisni, substantially asdescribed, the idler h, mounted on shaft h', and the idler i, inountedon a spindle on arm K, said arni being` adjustably secured to shaft h',substantially as shown and set forth.

In testimony whereof I affix niy signature in presence of two witnesses.
